Technical field

The invention relates to escalators or escalators.

BACKGROUND OF THE INVENTION

Such escalators are known from DE GM 88 02 483. These escalators have an illumination device which extends along the railing. Fluorescent luminaires that can extend under the handle rail and are used for illumination are listed.

In the escalator known from said utility model, the light source is preferably designed as an adjustable bulb with a nominal voltage of 24 volts. Such bulbs can serve illumination and provide an aesthetic design if they have different switching programs and, if necessary. the appropriate color scheme of the light bulbs to achieve the aesthetic overall impression desired by escalators and moving walkways with glass railings.

In many cases, however, supplementary illumination of the access / exit area of escalators is required by law. This lighting must also be fault-free in order to minimize the risk of injury present in these areas.

In this sense, it is known to illuminate the boarding / discharging target with incandescent lamps that are recessed in railing or fluorescent lamps. Such lighting devices can also be combined with lighting devices according to DE GM 88 02 483.

Since this lighting device - as opposed to illumination lighting, which is more for decorative purposes - is a safety-relevant feature, the maintenance regulations are accordingly strict. Accordingly, for safety reasons, incandescent lamps or fluorescent lamps must be replaced approximately half of their rated life, with appropriate replacement being carried out regularly for simplicity due to simplicity of maintenance.

However, this means - apart from wasting resources - additional maintenance costs, since the protective glass for the entry / exit area lighting equipment is usually vandal-proof and firmly integrated into the railing, so that the railing parts must be removed with appropriate special tools before changing the lighting equipment.

Furthermore, it is known to use light-emitting diodes for signaling danger or to signal certain information, whereby red light-emitting diodes are mostly used. These can be arranged in the fields and can be freely switchable in order, for example, to convey the required information according to the type of pictogram. However, such prior art systems were not suitable as active lighting devices.

Furthermore, it has already been proposed to use luminous light sources which are provided with a light guide for lighting and / or signaling purposes. The light guide can perform the desired light distribution, but based on the luminous intensity of the light source, which can, for example, be a xenon lamp

However, this solution would not be suitable to provide lighting for escalators both along the railing and for the entry / exit area.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide a escalator or a moving walkway according to the preamble of claim 1 having an illumination device that is substantially suitable for both illuminating or illuminating the handrail along the handrail as well as illuminating the entry / exit area.

This object is achieved according to the invention by claim 1. Preferred embodiments are part of the subclaims.

According to a particularly favorable effect of the invention, the same light emitting diodes can be used both for luminous illumination of the entry / exit area and for illumination, for example under the railing of escalators. Preferably, according to the invention, AlInAGaP or LEDs are used which have a luminous intensity of 9500 med as red, yellow and white light-emitting diodes and nevertheless have a luminous intensity of 1800 med as blue light-emitting diodes.

In order to avoid dazzling the occupants, but also to maintain a high degree of efficiency between illumination intensity and luminous intensity, it is preferable that the optical axis of the illumination device point at least in the region of the illumination illumination at an angle inward / inward. In the case of a double-sided arrangement of lighting devices, for example, the point of incident of the optical axis on the entry / exit area may lie at the border of one third of the width of the escalators or

According to a particularly advantageous aspect of the invention, the fluorescent lamps can be replaced in a substantially equivalent manner by the light-emitting diodes of the invention. For this purpose, the mounting units of the lighting devices are designed, which can be identical in size to, for example, a fluorescent lamp. These mounting units can then advantageously be used at the location where the fluorescent lamp has been used, e.g. both in the illumination area and in the illumination area.

It is also particularly advantageous that the light-emitting diodes according to the invention have an almost unlimited lifetime and, above all, they do not have to be replaced above the regular lifetime of escalators or escalators for safety reasons. Accordingly, light emitting diodes can be mounted rigidly, so that the risk of contact errors, which have always led to problems when using incandescent lamps as well as in prior art fluorescent lamps, has been greatly reduced, as the escalators have regularly exposed the handrail to certain shocks and vibrations.

Furthermore, the illumination device according to the invention is also shock-resistant when light-emitting diodes or LEDs, consisting of cast semiconductor elements, also resist shocks of a greater amount of G in the long term.

It is clear that by means of suitable and well-known switching techniques it must be ensured that the light-emitting diodes according to the invention do not suffer any overvoltage spikes and that, above all, the overvoltage spikes caused by the inductors of the escalator drive motors must be reduced to prevent light emitting diodes.

According to an extremely favorable and advantageous voltage supply system according to the invention, the light-emitting diodes are switched,

Even at a pulse / pause ratio of 1 to 1, the required supply current is halved. According to the invention, it is particularly advantageous in this context if the switching times of the light-emitting diode group coincide with the switching-off times of the other light-emitting diode group, so that a continuous supply current is essentially required, yet still produce the desired effects.

According to a further, particularly favorable aspect, the illumination device according to the invention can be provided with side reflective surfaces. These surfaces allow for deep-seated and thus vandal-resistant mounting, but still make good use of the transmitted light.
